BY W L" AT RNEY Patented Feb. 6, 1940 UNITED STATES PATENT oFEicE Thisinvention relates to improvements in all metal playground slides, andmore particularly to the construction of the side rails for the slidewhich will be formed to receive various thicknesses or gauges of steelbedways, and the pro` vision of novel means whereby the opposite sidesof the bedways will. be securely and rigidly clamped to the side railsso that the portions of the side rails which engage the upper surface ofthe bedway at its opposite sides, will form tight joints so that it willbe impossible for the dress material of the children using the slide tobesome caught between the bedway and the side rails of the slide.

An object of my invention is to provide an all metal playground slidehaving cooperating metal side rails adapted to receive steel bedways ofvarious thicknesses, and said side rails su'iciently flexible, so thatwhen a'plurality of locking bolts arey placed in the side rails, thetightening of the said bolts will cause the side rails to seat on orcontact the adjacent upper surface of the steel bedway in such a mannerthat line contacts will be effected so that there will be nopossibility` of the material forming the childrens clothing catching inthe slide as they use the same.

Another object of my invention is to provide an 4 improved all metalplayground slide which will combine side rails and an interchangeablebedway, which may be of various thicknesses, to-k gether with meansspaced along the side rails, whereby the said bedway may be tightlyclamped to the said side rails.

Other objects will appear as the description proceeds.

In the accompanying drawing which forms a part of my application,

Figure 1 is a sectional view taken on the line I-I of Figure 2;

Figure 2 is a sectional View taken on the line 2 2 of Figure 1;

Figure 3 is a sectional View taken on the line 3-3 of Figure 1;

Figure 4 is a perspective View partly in section of one of the siderails;

Figure 5 is a perspective view partly in section of one of the clampingrails adapted to be received in one of the side rails, and

Figure 6 is a perspective view partly in section of the bedway plate.

Like characters of reference are used throughout the followingspecification and the accompanying drawing to designate correspondingparts.

In carrying out my invention, I provide an all metal playground slidewhich Will include a pair of oppositely disposed side rails anda pair ofcoacting clamping rails received within the side rails and beingsuitably secured therein, together ,with a steel bedway plate which willbe iittedk between theside rails and clamped thereto by meanshereinafter described.

'The side railsl 'are of inverted U-shape, as clearly` shown in thedrawing, and when in position form parts of the slide, their outer sidearms 2 being slightlyy longer'than the inner side arms 3, therebyproviding adjustability and iexibility.

An elongated U-shape'locking plate 4 is received within the invertedU-shape side rail I adjacent-v its lower end, and is adapted t0 bearagainst the inner surfaces of the side rail arms 2 and 3, the lower endof the said locking plate or clamping rail being extended across thespace-between the terminal ends of the arms 2 `and 3, and is conofinverted U-shape, and is adapted to be re-r ceived or positioned withinthe clamping rail 4, and has Yits lowermost end resting on the uppervsurface of the portion 5 of the rail ri, and also is adapted to have anedge contact with the adjacent end of the rbedway plate 6.

Alined openings 8 and 9 will be formed at intervals in the upper crossor transverse portions of the clamping rails 4 and 1, respectively, and

are adapted to receive the threaded locking bolts IEI, which may bereadily inserted through the elongated openings II and I2, formed atintervals along the oppositerfsidesof the bedway plate 6 and in theportion 5 of the clamping rail 4, while Washers I3 will be employed nextthe head of the bolts III, and a cooperating nut or nut strip I4 havinga series of spaced threaded openings are provided for the threaded endsof the bolts, whereby tightening the bolts will cause the several partsof the side rail to flex until the bedway plate is firmly clamped inposition forming a line Contact with the adjacent portion 'of the siderail. Therefore, it will be seen that due to the exibility of theseveral parts forming the slide is being used. Cross braces l5 will beused to support the bedway plate B and reinforce the same, and arepositioned between the elongated openings Il in the opposite sides ofthe bedway plate 6.

It will be understod that I do not intend to limit myself to the specicconstruction described and shown in the drawing, as many minor changesin detail of construction may be resorted to without departure from thespirit of the invention.

Having thus described my invention what I claim as new and desire tosecure by Letters Patent of the United States is:

l. A side rail construction for playground slides including an invertedU-shape flexible side rail, the outermost arm of said side rail beingslightly longer than the inner arm thereof, a perforated locking andclamping plate supported in said side rail adapted to Contact saidlocking plate and having its lower side extending across and beyond thelower ends of the side rail, a bedway formed with spaced slots along itsedge adapted to be seated on the upper surface of the lower extendedside o the clamping plate, threaded bolts placeable through the slots inthe bedway and clamping plate adapted to be screwed through the upperportions of the locking and clamping plates, and a nut strip having aseries of threaded openings adapted to coact with the threaded bolts,whereby the tightening of the bolts will positively clamp bedways ofvarious thicknesses in position.

2. The subject matter as claimed in claim l, and the inner side of theinverted U-shape side rail when clamped to the bedway being adapted toseat down on and Contact in a tight line joint on the upper surface ofsaid bedway.
